Emperor's Game is played on a 10 x 10 board with two additional pieces - the General and The Adjutant. The General specifically is very powerful, being a combination of a Queen and Knight.
Pawns can advance up to three squares on their first movement. In addition, Emperor's Game adds an General and a Adjutant, which combine the power of a Knight with either a Queen or a Bishop.
The General like a Queen and a Knight combined.
The Adjutant moves like a Bishop and Knight combined
A Pawn can also promote to an General, Adjutant, Queen, Rook, Knight, or Bishop - but only if that piece has previously been captured.
The King moves 4 squares for queenside castling, and 3 squares for kingside.
In Emperor's Game a pawn can advance up to three squares on first movement, so En Passant captures can take place on any passed square.
